DRAFT: Split shared/dynamic libraries from static/build artifacts

Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

Closes #42

This PR separates the shared and dynamically loaded libraries in /lib and /plugins into a separate output from qt-main; this new output is called libqt5.

The purpose of creating this new output is to reduce the size of run exports for downstream packages which link to qt.

The size of the new libqt5 package is 31MB/100MB (compressed/uncompressed) which is about half the size of the current qt-main package (61MB/254MB).

As you can see from the diff, the build script is unchanged.

There is one change to the top-level build/host requirements: The libclang version is now manually pinned to 15 via the conda_build_config.yaml. This is because using pin_compatible in the outputs section causes an error in conda-build as noted in #223 (comment).

A new output section which splits the artifacts and dependencies using glob expressions.

Runtime dependencies on libraries who now have run_exports upstream were removed.

For testing, I have compared the artifacts using git, to identify added/missing files.

• linux64 - No significant difference; some pyc files are not packaged.
• osx64
• win64

Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipe) and found some lint.

Here's what I've got...

For recipe:

• Selectors are suggested to take a <two spaces>#<one space>[<expression>] form. See lines [263]

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

There is some problem with rendering the recipe due to the replacements key in the conda_build_config.yaml

This should be for the same reason why the main output is qt-main instead of qt

Suggested change

	- name: libqt5
	- name: libqt5-main

[carterbox]

Probably rerendering has broken the osx build because the vmImage has been updated.

@conda-forge/qt-main, before I move to the next step (trimming runtime dependencies). I need to know if this package split is correct. Are there also plugins or other binaries needed by end users at runtime located in $PREFIX/qml/**? Maybe I should add something like:

Suggested change

	- "{{ library }}plugins/**/*"
	- "{{ library }}plugins/**/*"
	- "{{ library }}**/*plugin.so"
